9. The switching device of claim 8, wherein the push assembly comprises:
the moving part is connected with the driving component;
the pushing column is connected with the moving part at one end, the cover plate is movably arranged at the other end in a penetrating mode, and the driving assembly is used for driving the moving part to move.
10. The switching device according to claim 9, wherein the drive assembly comprises:
the sliding rail is arranged on the equipment body, and the moving piece is connected to the sliding rail in a sliding manner;
the transmission part is connected to the moving part;
the driving piece is connected to the transmission piece and used for driving the transmission piece to move so that the transmission piece drives the moving piece to linearly move along the sliding rail;
the sensor is arranged on the equipment body and used for sensing that the moving piece or the cover plate is in place and feeding back a signal when the cover plate moves to completely open the opening;
and the controller is in communication connection with the inductor and is used for receiving a feedback signal of the inductor and controlling the driving of the driving piece.
11. A centrifuge, comprising a switching device according to any one of claims 1-10.
12. A liquid-based sheet producing apparatus comprising the centrifuge according to claim 11.
